A mirroring technique for SANs in a metro WDM ring under different traffic scenarios
This paper presents a new data mirroring technique for storage area networks (SANs) in a metropolitan area wavelength division multiplexing (WDM) ring. Two sectioning links are introduced to the ring to help deal with the hot-node scenario created by the SAN nodes and their mirrors. The performance is evaluated through simulation of a network of 24 nodes, 6 wavelengths with 1 Gb/s access node rate and 5 Gb/s SAN node rate under different traffic asymmetries. In addition to the fixed-size (FS) slot scheme, performance is evaluated under two different schemes accommodating variable size packet traffic - variable-size (VS) slot and super-size (SS) slot schemes. Results of average node throughput, queuing delay and transmission buffers packet dropping probability are presented and analyzed.
